More alleged thylacine spottings have been reported to the ABC Radio's wildlife expert Gary Opit.
Officially they no longer exist, but that hasn't stopped wildlife watchers spotting thylacines in northern New South Wales.
Also known as tasmanian tigers, the last known thylacine is believed to have died in a Hobart zoo in 1936.
Since then, there have been hundreds of unconfirmed sightings of the animals across Australia, including a handful around Nimbin in recent weeks.
ABC North Coast wildlife expert Gary Opit says the recent spotters insisted the mysterious animals were not dogs, cats or foxes.
"It's not a dog or a cat, but it's about the size of a dog," he says.
"It's described as having a banded tail, a greyish animal with stripes across the tail and stripes along the flank."
Gary hopes the rise in popularity of smartphones will mean that eventually someone can capture the creature on camera.
"It's usually always the same thing, people driving their car and an animal they've never seen before crosses in front of them," he says.
"People are always adamant it's not a dog.
"No one has ever been able to get a photo of one, so we don't know what it is or if it really exists, but the fact that people keep reporting them is interesting."
